IMPROVEMENTINMACHINERY FOR DESICQATING sees.

Specification forming part of Letters Patent No. 184,188, dated November 7, 1876; application filed March 31, 1876.

' chinery for applying blasts of air in the desiccation of eggs and for other purposes and I do hereby declare the following to be a full,

clear, and exact description of the invention,-

such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification, in Which- Figure 1 is a front elevation of an apparatus embodying myimprovements. Fig. 2 is a vertical transverse section therough same.

Whenever, in machinery used for the application of a blast or blasts, current or currents, of air, heated or otherwise, any such blast or current is to be applied or delivered through a longitudinal slot, mouth, or flattened pipe, it is desirable that such delivery or application should be approximately uniform and even throughout the extent of each such slot, mouth, or flattened pipe. Should the machinery indicated be of any considerable extent, its several parts or sections, or more or less distinct machines, will, of necessity, be placed at varying distances from theblower or other agency employed in causing or propelling the moving column of air to be utilized; and yet it is desirable, in various manufactures, that the currents or blasts of air should be of approximately uniform .force and efficiency at the point of their delivery or application.

To obtain the results thus set forth, and in a simple and inexpensive manner, is the object of my invention.

I employ for this purpose, and for each separate set of sections or parts, or more or less distinct pieces of machinery, a main air tube, pipe, or conduit, as B, Figs. 1 and 2, into and through which the air is forced or caused to flow by any of the ordinary and known methods or machinery. At suitable points on this main tube, pipe, or conduit, as D, Figs. 1 and 2, 1 construct and open from it subsidiary feeding-pipes, as shown, proportioned in size to that of the main pipe, and to the volume and force of air required and attainable, and' force and volume of the current of air pass-' ing through any subsidiary feeding-pipe by means of a simple cook or valve, as E, Figs. 1 and 2. Each air chamber or reservoir is provided with a slot or slots, mouth or mouths,

as F, Figs. 1 and 2, for the delivery and application of the supply of air for the purposes indicated. Each'and every such air chamber or reservoir should be, in' its least diameter, not less than double the least diameter of the subsidiary feeding pipe D, by which it is supplied. Where the shape of the machinery used permits the use of the cylindrical shape in the construction of any such air chamber or reservoir, for the purposes indicated, the slot or slots, mouth or months, should be opened on lines parallel to the axis of such cylinder, and, if more than one, nearly equally distant from the center of the mouth of the subsidiary feeding-pipe D. The air contained in the air chamber or reservoir A being of approximately uniform density and a perfect fluid, the pressure of the current or blast entering through the subsidiary feeding-pipe D is at once communicated to the entire volume, and to every part of the air so contained, and the expulsion or escape of the same through the slots or mouths F becomes approximately uniform and even throughout the entire extent of said slots or mouths, and throughout the extent of any flattened pipe or pipes attached to them, for the purposes indicated.

1 claim as my invention- 1. The improved apparatus for effecting an even, uniform, and equal delivery of a blast or blasts of air, consisting essentially of the,

main reservoir or chest B, supply pipe or 2 lS LlSS pipes D, and the receiving and delivery res- F, of narrow elongated shape, parallel with ervoir A, having one or more elongated disthe axis of said cylinder, andadapted to the charge-openings, F, extending lengthwise of discharge of air from the interior of the latthe axis of said reservoir, substantially as deter, substantially as described.

scribed. In testimony that I claim the foregoing I 2. In combination with the main air reserhave hereunto set my hand this 23d day of voir or chest'B and the subsidiary feeding March, 1876.

pipe or pipes D, having controlling valve E, WILLIAM O. STODDARD. the receiving and delivery reservoir A, con- Witnesses: sisting of a horizontal cylinder of elongated LUCIEN BIRDSEYE, form, having a discharge opening or aperture, BENJ. H. BAYLISS.
